CURLING-IRONB Specification of Letters Patent,

Patented March 5, 1907.

Application file-.1 August 19, 1905. Serial No- 274,879.

To all whom it may concern:

- .Be it known that I, GEORGE F. SHIELDS, a citizen of the United States, residing at'ltern in the county of Kern, State of California, have invented certain new and useful Imrovements in Curlin -Irons and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to electric curlingirons, and has for its object to improve the construction shown in my prior patent, No. 784,438, dated March 7, 1905.

To this end the invention consists in the format-ion of a handle in two sections, each of which is provided with a registering bore and with a pair of recesses communicating therewith, whereby the binding-posts, supply-wires, and resistance-coil may be more readily and perfectly aflixed in place than has heretofore been possible where asolid or one-piece handle has been in use.

The invention further consists in theconstruction, combination, and arrangement of parts, all as hereinafter fully described, speci'fically claimed, and illustrated in the accompanying drawings, it being understood I that changes in form, proportion, size, and

minor details may be made withinthe sco e of the claims without departing from tlie s irit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a longitudi-' nal sectional view of my invention. is a transverse sectional view.

Referring now more particularly to the accompanying drawings, the reference character 1 designates a handle having a longitudinal bore 2 therethrough, in which bore are formedthe recesses 3 and 4, one recess being arranged in advance of the o.ther.' A tube 5, of glass, porcelain, or any'othe-r suitable material, has one of its ends in the aforesaid longitudinal bore 2 of the handle 1, with its 0 posite or outer end closed as indicated .by t e reference character 6. This tube 5 is filled with suitable insulating material 7, and embedded in this insulating material is a heating-coil 8, which by reason of the insulating material 7 is held from engagement with the inner surfaces of the tube 5, The oppositely-disposed terminals 9 and it of the heating-coil 8 pass through the open end of the tube 5 and are connected with short binding-posts 11 and 12, respectively, which binding-posts are disposed in therespective recesses 13 and 4 of the bore 2 of the handle 1.

Circuit-wires '13 and 14 are connected to the A respective binding-posts 11 and 12 and lead outwardly through the open end of the handle 1 opposite the end in which the aforesaid tube 5 is inserted for connection with a suitable battery to direct the current into the heating-coil 8 for heating the tube 5. 'ihis tube 5 also serves as a clamping, member.

Thehandle 1. 1s composed of two members '15 and 16, which are connected together at one end through the instrumentality of a suitable fastener 17, which passes between the coils 18 of the circuit-wires 13 and 14,415 shown in the drawings, the opposite ends of 'the members of the handle being clamped together by means of. a suitable ferrule 19, which latter is provided with a pair of ears 20, in which is pivotally mounted, by means of a suitable pivot-pin 21, a clamping member 22, provided with an integral handle 23, there being a bent flat spring having its leaf 24 disposed against the under face of the handle 23 immediately in the rear of the'said pivot-pin 21, with its opposite leaf 25 secured to the handle 1 by means'ofa'stitable fastener26 immediately in the rear of the ferrule- 19. by reason ofv the bent flat spling just alluded to the handle 23 is held out of engagement with the handle 1 and the clamping member 22 in engagement with the tube or clam ing member 5.

Owing to t e section formation of the handle, as has been-described, and to the formation of the several recesses, the binding-posts may be aflixed in the member 15 and connected with the terminals of the supply and heating wires before the opposite section 16 is ositioned and secured by the ferrule and bolt, thus positively insuring a perfect connection of the several wires and at the same 'dle formed of a pair of sections each of Which is provided with a longitudinal bore and with a pairof recesses intermediate the ends of sand bore and communicating therewith, the recesses and bores registering When the sec' .t ons are secured together; binding-posts arranged in the recesses of one member and extending intothe recesses in the o posite mem-' her; a tubular clamping mem er; a heatin -coil in said'clampin% member, the termina s of the heating-coil eing' connected With eeasse the binding-posts; circuitwires connecting" the binding-posts and leading outwardly. of the bore of the handle; a ferrule embracing the sections of the handle, said ferrule having spaced ears; a second clamping member pivotally'mounted in the ears of said ferrule and providedwith a handle; and a spring ar-' ranged between the handles to hold the clamping members in engagement with each other.

In testimony whereof I afiix'my signature in presence of tWo WitIlGSSES;

' GEORGE F. SHIELDS.
